A door is a hinged or otherwise movable barrier that allows ingress and egress into an enclosure. The opening in the wall can be referred to as a "portal". A door's essential and primary purpose is to provide security by controlling access to the portal (doorway). Conventionally, it is a panel that fits into the portal of a building, room, or vehicle.
